I'm repairing a 512k with video issues for somebody, and when I disassembled the machine to get at the analog board, I discovered that the white plastic shield with the adjustment labels on it was held on with double-sided tape rather than the usual plastic push pins. Has anyone seen this before? Would it have likely came from the factory this way, or was this likely to be a later repair job? The machine has clearly been opened before since the floppy drive is an MF-D51W instead of the original OA-D34V type, and the logic board has some 1985 datecode ICs despite the machine having an '84 serial number. The holes where the pushpins would go are drilled in both the PCB and the plastic sheet, so the only explanations I can think of is that this was a hack done after somebody lost the pushpins, or maybe the factory was out of pins.

512k analog board shield held on with double-sided tape?

128ks all had tape. 512ks did too I am pretty sure. Pluses are a hit an miss. Early, possibly all, did. Later it seems all - about the time the SE came out. I could be wrong, but I dont recall seeing the foam tape in any SE.
MacDrone - you could be right, but I dont recall every seeing a 512k with pins. At least not one with an original analog board. Keep in mind many a 128k and 512k got plus boards when the originals failed.

my 512k has pins, but it's possible it has had the analog board swapped (As I got it from the stock from a old repair shop, and it had been upgraded with a plus board when I got it)
My Plus on the other hand is taped (I always assumed this was because the analog had been worked on, but now it seems it was probably like that from the factory) It's a early '87 s/n iirc, so it would probably make sense for it to be taped
